Digital Arts contributor Lizzie Mary Cullen has been busy working on a five-day live art project to create a giant Mother's day card as part of Oxfam's Mother Appeal.

The Happiest Mother's Day Card is a collaboration between creative agency Proximity London, production and creative tech company Grand Visual and artist Lizzie Mary Cullen, who'll be turning public Mother's day dedications into a giant piece of art before our very eyes.

From 19 March, members of the public have been able to dedicate a square of Lizzie's canvas to their mum via the happiestmothersdaycard.org website. In order to allow the public to do so, Grand Visual had to come up with a way to ensure that the squares dedicated would be perfectly synched with the live card.

To achieve this, Grand Visual used a robotic panhead camera to capture Lizzie's physical canvas, which is overlaid with a digital grid system that links with the website (as shown above) and projected onto the canvas and will expand as dedications come in. There will be a live video stream as the card takes shape, so participants can see their square as it's being painted.

The aim is to break the world record for the most contributions for a greetings card, which is what the giant canvas will become. The current official Guinness World Record is 5,339 contributions, so Lizzie and the team will need to beat that number to make the record their own.

It seems as though the project is on track to beat the record, with 2840 dedications already being made as of 10:45 on 21 March with two days left of the project.
